Issue #34 - Unit and e2e tests for CopyButton component

[priscilauchoa]

Issue #34

Description

Test suite for CopyButton.vue component (./src/components/CopyButton.vue) using Jest to Unit Test and Nightwatch to e2e. The function of this button is to copy the content of a specific element.

• unit tests: Ensure proper initial and click rendering as well as the success and failing event dispatch.
• e2e tests: Covers the whole CopyButton flow, from start to end in both usages, copy Rich Text and HTML.

Other information
It was necessary to mock an environment to clipboard.js library on unit tests, because some inner functions from clipboard.js required some api methods from window and document browser objects, unavailable on Jest.

Checklist

• My code follows the style guidelines of this project
• I added tests thinking about the success of inputs and outputs of content brought through click events in this button.
• I added tests thinking about the button behavior.
